An apparatus for detecting icing conditions on an aircraft includes a laser system configured to direct a light signal into a cloud, a lens component configured to collect echo signals from a cloud caused by the light signal directed into the cloud, a beam splitter component configured to redirect signals received and passing through the lens component into at least first and second paths and a supercooled large droplet (SLD) detector to receive the redirected signals. The SLD includes a first signal detector component configured to perform a first color measurement on the first redirected signal, and a second signal detector component configured to perform a second color measurement on the second redirected signal. The SLD detector is configured to use the first and second color measurements to determine liquid water content and droplet diameter distribution for the cloud.

An immiscible lipophilic or hydrophilic liquid phase separated respectively from a continuous hydrophilic phase or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are mixed, layered, etc., and formed into a filter. The separation mechanism involves capture of small droplets of the immiscible phase, coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. With respect to separation of a hydrophilic immiscible fluid such as water in a lipophilic continuous fluid such as oil, the hydrophobic fibers will cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets are formed on hydrophilic surface. The large droplets stay on hydrophilic fiber surface for extended periods of time and continue to coalescence until they are so large that they can no longer be maintained by the hydrophilic fibers and are released and drained off of the filter. In designing such filter, wettability of the filter media is an important parameter. The filter media can be designed by mixing hydrophilic and hydrophobic fibers in various proportions to achieve an optimum wettability range for separation of the immiscible liquid from the continuous phase liquid. The wettability of filter media can be characterized by a modified Washburn Equation.

The present invention provides an image processing method including a conversion step of converting multilevel data of an image into a dot pattern using a multilevel error diffusion process. The conversion step includes the steps of determining a pixel corresponding to an abnormal nozzle based on abnormal nozzle information provided for each of droplet sizes supported by nozzles of an image forming apparatus; preventing jetting of a droplet onto the determined pixel; distributing a quantization error of the determined pixel calculated in the multilevel error diffusion process to neighboring pixels; and if extra- large droplets with a droplet size greater than the droplet size of a full-size droplet capable of filling a pixel are to be formed in the neighboring pixels as a result of distributing the quantization error, removing one or more of the extra-large droplets or reducing the droplet size of one or more of the extra-large droplets.

A compact liquid ejection recording head capable of forming high-quality images at high speed includes large nozzles for ejecting large droplets, medium nozzles for ejecting medium droplets, and small nozzles for ejecting small droplets. The large nozzles are arranged on one side of an ink supply port, while the small nozzles and the medium nozzles are arranged on the other side of the ink supply port. The number of the small nozzles is larger than that of the medium nozzles, and that of the large nozzles. This allows high-quality and high-speed printing using the small nozzles, high-speed photo printing using the medium and small nozzles, and high-speed printing using the large nozzles.

A system for detecting ice or supercooled large droplets within an area of interest having a detection system measuring radiance or reflectance of the area of interest when exposed to shortwave infrared radiation having a wavelength in the range of about 2.05 μm to about 2.30 μm. The detection system measures the radiance or reflectance in a first band having a wavelength in the range of about 2.05 μm to about 2.15 μm and outputting a first band signal, and further measures the radiance or reflectance in a second band having a wavelength in the range of about 2.15 μm to about 2.30 μm and outputting a second band signal. A processing unit determines a ratio of the first band signal and the second band signal and compares the ratio to a predetermined critical ratio and outputs a determination signal indicating presence of ice or supercooled water droplets.
